Application filed November 15, 1920.

To @ZZ 107mm it may concern Be it known that l, HENRY ENGAU, a citizenof the United States of America, residing at New York, N. Y., haveinvented a new and useful Stamping Press, of which the following is aspecification.

My invention relates to a stamping press, and is particularly adaptedfor stamping letters, characters, dies, etc., in gold, silver oraluminum foil on book covers, leather goods in general, such as wallets7bags, and

all yarticles made of leather, book cloths, silk, etc.

lt is an object of my invent-ion to provide a stamping press inV whichthe operating members are all positioned within easy reach of theoperator.

lt is a further object to provide a machine in which the downward limitof the stamp* ing` stroke yof the stamping head may be accurately andeasily` pre-detern'iined.

And in general, the object is to provide a very serviceable andconvenient press for performing work above described.

In the preferred form of my invention, there is provided a main frameand platen for supporting the operative parts of myv machine. 1l headcarrier is supported from the frame, and a stamping head is mounted formovementl on said head carrier. A lever is provided for actuating thestamping head, and anti-friction means may be interposed between theoperating lever and the head. Adjustable means are provided forpermitting the downward limit of the stroke of the head to be accuratelypre-determined.

In the illustrative form shown in the drawings:

Figure 1 is a side elevation of a stamping press showing features oftheinvention.

Fig. 2 is a section taken in the plane of the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragment-ary detail view of a means for moving astamping head.

In said drawings, 5 indicates any suitable form of base or platen andstandards 6*-7 preferably four in number, are supported from the platen.Secured to the upper end of the standards 6 7 are two crossbeains 8 9which complete the framework and provide the space or opening betweenthe standards and beams for containing; the main working parts of thepress.

Supported from the beams is shown a semi 1ro. 424,006.

carrier head 10 from which a stamping head 11 .may be suitablysupported. In the forni shown, l. haveprovided guides 12 for s'ecuringthe head 11 to the head carrier in sliding relation. fr pallet forholding the letters or characters 13 is removably supported from thelower end of the stamping head. The head maybe provided with an aperture14, and the pallet has a handle 15, which is positioned in the opening,and the latter prov`des ample space for the insertion of the hand whenit is desired to apply or remove the pallet from the stamping head. Anysuitable means such as spring 16 may hold the pallet to the stampinghead. The upper end of the head is preferably inclined as indicated at17.

A; lever 18 is used to actuate the stamping' head. rThis lever may beconveniently pivoted as at 19 to a crosshead 2O which may be adjustablysupported from the head carrier 10. '.lhe crosshead 20 may be providedwith a slot or opening 21 in which positioned an arm or lever 22carrying anti-friction means such as a roller 23. Means such as thepivot pin 24 of the roller may secure the lever 18 and 22 together, orthe arm 22 may be dispensed with and the roller carried directly by theVlever 1S.

A screw carrying a gear 26 passes 85 through the head carrier 10 andengages the crosshead 20 for vmoving the latter up or down. Cooperatingwith the gear 26 is a. gear 27 supported from the shaft 28 and anysuitable means such as the hand-wheel 29 may be provided for rotating)`the `gears 27-26 and adjusting the erosshead 2() up or down. Means areprovided for constantly urging the stamping head upwardly, the meansshown in the preferred form consisting of a bar 30 secured to thestandard 7 at one end, and having the other end 31 engaging the upperedge of the opening 14: in the stamping head, and a spring such as 32draws upwardly on the bar 30, and consequently urges the head 11upwardly.

ln order to hea-t the pallet to secure a better impression on some ofgoods. a burner 33 may be secured to the lower end of the stamping headin order te heat the type or characters.

indicates any suitable type of supporting device or holder for the workB5, and suitable guides 136 mayv be provided for positioning the devicein the desired location. 11G

The operation of my machine is as fol lows:-

The article to be stamped is secured in the vise 34 and positioned inthe proper location beneath the stampinghead. The pallet is heated bymeans of the burner 33 or otherwise. The handle 18 is then drawn towardthe left as viewed in Fig. 2, and the roller riding upon the surface 17depresses the head until a line joining the points 19 and 24 is normalto the surface 17, after which continued movement to the left wouldpermit the stamping head to rise. By means of the hand-wheel 29 withinconvenient reach of the operator, the crosshead 20 may be adjusted, andthe downward limit of the stamping head may be accurately predeterminedIt will thus be seen that with proper adjustment of the crossheadnothing is left to the sense of touch of the operator in performingl thestamping` operation, since the lever may be drawn entirely across themachine without moving the stamping head beyond the predeterminedposition. Y

It will be noted .that l have provided a stamping press in which all ofthe operating elements are positioned within convenient reach of theoperator, and one in which but little is left to the sense of touch ofthe operator.

While l have described in detail a specific form of my invention, l donot wish to be limited to the specific form shown, for various changesand modifications may be made, all within the scope ot the appendedclaims. l

I claim:

1. In a machine of the character described,

' a frame, a head carrier supported by said frame, a stamping headcarried by said head carrier and carrying stamping characters, anadjustable crosshead carried by said head carrier, a lever pivotallymounted on said crosshead, aroller secured. to said lever and movabletherewith for cooperation with said stamping head, and means for.adjusting said crosshead. A

2. ln a. stamping press, ahead carrier supported from a frame, astamping head carried by said carrier, a pallet removably rcarried bysaid head, means carried by said stamping head forheating said pallet,and anti-friction means formoving said head.

3. ln a stamping press, a head carrier supported from a frame, astamping head movable on said carrier, a, lever pivoted adjacent saidstamping head and a roller carried by one of said two last mentionedmembers and co-operating with the other of said two members for movingthe stamping head when the lever is actuated, said lever serving to movethe head in one direction when the lever is moved. in one direction, andserving to permit the head to move in the opposite direction when themovement of the lever in the irst mentioned direction is continued.

4. ln a stampingpress,a frame having an pening therein, a head carriersupported from said frame, a head movable on said carrier, a` leverpivota'lly mounted adjacent said carrier and movable in the opening insaid frame, a roller movable with said lever for actuating the head andmanual means for adjusting the pivotal mounting of said lever, saidmanual means being. positioned in the opening in said frame.

5. In a stamping press, a frame, a head carrier supported from said`trame, a stamping head movable on said head carrier, a crossheadmounted on said head carrier, a lever carrying aI roller mounted on saidcrosshead, a screw for moving said crosshead, a pair ot gearscooperating with said screw, and a handle secured lto one of said gearsand positioned within easy reach of an operator for adjusting saidcrosshead.
